When we make attribute combinations, we need a way to change the shipping sizes.
Example -
I could have a foam mattress of different sizes. In the drop down for attributes I pick a size.
Obviously a twin bed is going to be much smaller than a king bed.
If we could simply adjust the size on the attributes or attribute combinations, that would be very helpful for shipping.
As it is now we are pretty much forced to do separate products to account for the shipping when attributes would work if they had this simple option.
